Just got the tweak Unlockr and at first look I was a fan. Really wish that it was as safe as a normal slide to unlock and password system that Apple provides. In just a few seconds I was able to bypass it. The steps to bypass it are.
1) set a code and lock the phone.
2) press the wake button.
3) slide the camera grabber up.
4) press the home button.
5) boom your in the phone.
Let’s hope this gets fixed ASAP.
